TT Selection: Balanced
Both systems with balanced gain

The Sovtek 12AX7WA is a defacto standard in 12AX7 tubes for many years yet because of its high dependability and its low noise floor.

TT Selection: Balanced
Both systems with balanced gain

Sweet and warm sounding preamp tube with high gain. We recommend this tube for guitar/bass amps.
